How To Test The CKP Sensor (1995-1998 1.5L Toyota Tercel)

Page 2 of 2

TEST 2: Testing The CKP Sensor's Output With A Multimeter

In this last test section we'll do a multimeter output test (with the multimeter in Volts AC mode).

The CKP sensor should output an AC voltage of about 0.4 to 1.2 Volts AC as you crank the engine.

If the CKP is bad, your multimeter will report 0 AC volts when you crank the engine.

IMPORTANT: Your Toyota Tercel's battery should be fully charged before commencing this test.

These are the test steps:

1
Disconnect the CKP sensor from its electrical connector.

LOCATION: The CKP sensor's connector is located on the right side of the intake manifold (near fuel injector #1).
2
Place your multimeter in Volts AC mode.
3
With your multimeter test leads, probe the male spade terminals of the CKP sensor's connector.

NOTE: You're probing the male spade terminals of the CKP sensor connector and NOT the female terminals of the engine wiring harness connector.
4
Have a helper crank the engine as you observe the multimeter.

CAUTION: Be careful and stay alert as the engine is cranking.
5
The multimeter should report an AC voltage that will oscillate somewhere around 0.4 to 1.2 Volts AC.

Let's take a look at what your test results mean:

CASE 1: The multimeter reported the indicated AC voltage. This test result confirms that the CKP sensor is functioning correctly.

If your Toyota Tercel does not start, take a look at the following engine no-start diagnostic tutorial:

CASE 2: The multimeter reported 0 AC voltage. This test result confirms that the crankshaft position sensor is bad and needs replacement.
